Discord blocked by Antivirus

Discord files are usually located within the AppData folder, protected by the antivirus as a system folder. As settings on each antivirus can differ, there’s a chance that yours may have blocked Discord from installing or even updating properly.

This can result in a Discord fatal javascript error with your antivirus quarantining the files. To prevent this from happening, you can enable Discord in your antivirus settings or make an exception for it.
